Serial Killers — Tag Meaning
A canonical tag native to crime and thriller fandoms, covering works where a serial murderer is antagonist, subject, or, in darker corners, protagonist. Certain fandoms built around such characters use it as a basic descriptive tag.
What to Expect From "Serial Killers" Fics
Multiple killings and a narrative engaged with the killer's psychology, at a distance or uncomfortably close. Dark-protagonist works should carry additional warnings.

Murder
A canonical tag for unlawful killing within the work, whether the fic follows the killer, the investigators, or the bereaved. Crime fandoms use it descriptively; others use it to warn that a death is violent and intentional.

Psychological Horror
Horror that works on the mind rather than the body: paranoia, gaslighting, unreliable perception, the slow erosion of a character's grip on reality. Authors choose it over plain Horror to signal that the scares come from dread and disorientation, not monsters or gore.

Dark
A tonal warning that the fic ventures into bleak, disturbing, or morally ugly territory beyond what its fandom usually entertains. It frequently modifies a character ('dark' versions of heroes) or an entire premise, and conscientious authors pair it with specific warnings about what makes it dark.

Violence
A general-purpose flag for violent content that exceeds the incidental but may not warrant the archive's Graphic Depictions warning. Authors use it to cover fights, assaults, and brutality, trusting readers to combine it with the fic's rating to judge intensity.
